Expand description
The field type represents a field in the form-data that is allowed to be parsed.

Array(Array<T, E>)
Map(Map<T, E>)
File(Arc<dyn Fn(String, Mime, Pin<Box<dyn Stream<Item = Result<Bytes, Error>>>>) -> Pin<Box<dyn Future<Output = Result<T, E>>>> + Send + Sync>)
Tuple Fields
Bytes
Int
Float
Text
Implementations
Add a File field with a name generator.
The name generator will be called for each file matching this field’s key. Keep in mind that each key/file pair will have it’s own name-generator, so sharing a name-generator between fields is up to the user.
Example
let (tx, rx) = channel(1);
let form = Form::new().field("file-field", Field::file(move |_, _, mut stream| {
let mut tx = tx.clone();
async move {
while let Some(res) = stream.next().await {
if let Ok(bytes) = res {
if let Err(_) = tx.send(bytes).await {
break;
}
}
}
Ok(()) as Result<_, Error>
}
}));
Add a Bytes field to a form
Example
let form = Form::<(), Error>::new().field("text-field", Field::bytes());
Add a Text field to a form
Example
let form = Form::<(), Error>::new().field("text-field", Field::text());
Add an Int field to a form
Example
let form = Form::<(), Error>::new().field("int-field", Field::int());
Add a Float field to a form
Example
let form = Form::<(), Error>::new().field("float-field", Field::float());
Add an Array to a form
Example
let form = Form::<(), Error>::new()
.field(
"array-field",
Field::array(Field::text())
);
